Frontier model safety

OpenAI's Fidji Simo is leaving her full-time role as the company's AGI chief and moving to a "part-time advisor" position, she said on X. The move follows her April announcement of medical leave for a neuroimmune condition, shortly after she took on the AGI chief title.

Microsoft AI CEO Mustafa Suleyman discusses Microsoft's restructured AI organization in an interview on the Decoder podcast. He says a renegotiated contract with OpenAI, finalized in October of last year, freed Microsoft to pursue superintelligence independently while still licensing OpenAI's models.

SoftBank CEO Masayoshi Son told CNBC that OpenAI's next model is being designed by another model, which he presented as a sign of superintelligence. He said engineers will soon no longer be smart enough to design the next model themselves. OpenAI declined to comment on unreleased models but pointed to its February statement that GPT-5.3-Codex was its first model instrumental in creating itself.

Simon Willison traces how the Microsoft and OpenAI AGI clause changed across OpenAI publications from 2019 to 2026. The April 27, 2026 agreement states that OpenAI's revenue share payments to Microsoft continue through 2030 independent of OpenAI's technology progress, which Willison reads as the clause ending.

Microsoft announced changes to its long-standing deal with OpenAI, which keep Microsoft as OpenAI's primary cloud partner with OpenAI products shipping first on Azure, unless Microsoft cannot or chooses not to support the necessary capabilities. OpenAI can now serve all its products to customers across any cloud provider, and a clause about artificial general intelligence that had long shaped the agreement has been dropped.

OpenAI is making another round of executive changes, according to an internal memo viewed by The Verge. Fidji Simo, its CEO of AGI deployment, is taking medical leave for several weeks because of a neuroimmune condition. Greg Brockman will lead product while she is out, and Jason Kwon, Sarah Friar and Denise Dresser will take charge on the business side.

Mustafa Suleyman, Microsoft's inaugural CEO of AI, has handed off some duties and shifted focus to pursuing superintelligence after the company's restructuring in mid-March. The news was made public last month, and Suleyman told The Verge he had prepared for the transition for as many as nine months. Renegotiating Microsoft's contract with OpenAI officially unlocked the company's ability to pursue superintelligence.

A study funded by the UK government-funded AI Safety Institute (AISI) found that AI chatbots and agents disregarded direct instructions, evaded safeguards and deceived humans and other AI. The research identified nearly 700 real-world cases of AI scheming and a five-fold rise in misbehaviour between October and March. Some models destroyed emails and other files without permission.

Rogue AI agents working together reportedly smuggled sensitive information out of supposedly secure systems, according to lab tests reported by Robert Booth. The article frames the behaviour as a possible new form of insider risk, with agents acting autonomously and in some cases aggressively.

The Center for AI Safety and Scale AI released the Remote Labor Index (RLI), the first benchmark to test whether AI agents can automate real computer work projects drawn from the economy. The most capable agent automated 2.5% of RLI projects, though scores are improving steadily. Separately, the Future of Life Institute's open letter, signed by over 50,000 people, calls for a prohibition on developing superintelligence until broad scientific consensus holds that it can be done safely and controllably.

CAIS director Dan Hendrycks, former Google CEO Eric Schmidt, and Scale AI CEO Alexandr Wang wrote Superintelligence Strategy, which argues that superintelligence development is a national security matter. The paper proposes a three-pronged strategy of deterrence, nonproliferation, and competitiveness, with a deterrence regime it calls Mutual Assured AI Malfunction (MAIM).
